Abstract
The objective of the study was to evaluate the efficacy and toxicity of Temozolomide (TMZ) administered for 5 consecutive days in three daily dosing in children with recurrent or refractory high-grade glioma.Twenty-four patients with a median age of 10.5 years were enrolled onto this open-label, multicenter, phase II study. The patients were previously treated with surgical resection (17 of 24), radiotherapy (19 of 24) and chemotherapy (18 of 24). Therapy was administered orally three times a day for 5 consecutive days at the dose of 200 mg/m2/d×5 for chemotherapy naive patients. In patients heavily pretreated with chemotherapy the starting dose was of 150 mg/m2/d×5.A total of 95 cycles were administered. The median progression free-survival (PFS) was 3 months for the entire group while disease stabilization was obtained in 7 patients (29.1%), all with supratentorial tumors. No CR or PR was observed. TMZ treatment showed a limited toxicity. Thrombocytopenia was the most common hematological adverse effect.Our data suggest a marginal activity of TMZ in children with recurrent high-grade glioma.
